Kodos 1.1 released - Regular expression visual debugger for Python
by stuff＠nonpoint.mailzilla.net 16 Apr '03

16 Apr '03

Kodos 1.1 has been released and is available at: http://kodos.sourceforge.net Kodos is a regular expression designer, tester, debugger and validator that allows a developer to create and modify regular expressions against a test string. The intuitive interface allows the developer the ability to modify the regular expression (regex) and to see the effects against their test string in real-time. Key Features: - Matches can be easily viewed and each match can be seen distinctly - Regex groups and named groups are clearly displayed - Sample source code is shown so even python developers new to regular expressions can quickly add the produced regular expressions to their own projects. - Ability to load and save your test cases - Kodos relies on PyQt for the GUI elements. Changes since 1.0: Added the ability to (un)pause regex processing. Added "import file" option to file menu. Added a bug reporting mechanism within the application Added an additional preference (email server) to the preferences menu (for use with the bug reporting window). Fixed tabbing issue within preferences). Added a 3 second timeout for editing (may eventually move this to preferences). I've been able to produce situations where the findall and search (with a non 0 start) methods of the compiled re object take awhile to complete. This timeout fixes these situations. I've also uncovered a case where the re (python2.1 and python2.2, maybe others) locks up entirely (perhaps an infinite loop). Unfortunately, the timeout doesn't fix this event (since control never yields from this re method, furthermore, the alarm signal is never fired) and it causes Kodos to freeze. Currently, I don't have a solution for this but I'm not sure if anyone is experiencing this problem (this seems to be a python re bug and not specifically a Kodos bug, however, it would be nice if it could be handled gracefully). Code cleanup. All windows share the same Kodos toolbar text logo (previously, there was a disconnect between main window, help and reference windows). Fixed a bug that prevented Kodos from launching if used with PyQt (Qt) 2.x

ANN: Coil 0.2 - an MVC framework
by Jeff Simpson 15 Apr '03

15 Apr '03

Coil is an MVC framework for the Python programming language. Coil is based largely on the ideas and design of Struts. Coil allows you to cleanly separate the model, view and controller via an XML configuration file. Coil is currently alpha quality, but usable. There is a very basic login example in the source tarball demonstrating the basic work flow. I am currently building an mp3 server to use as a better demo. For more information please visit the SourceForge site, http://sourceforge.net/projects/coil/ Supported Features ------------------ - Cheetah supported for the "view" - Form objects with validation support - Action objects for controller abstraction - DispatchAction support which allows multiple method entry points on the same action object - ActionForward for abstracting a page location by name TODO ---- - Better Spyce support (currently some hacks are required to make Spyce work with Coil) - Message Resources (externalized data used in view) - Dynamic forms - Better configuration parser - Locale support - Datasource support - Enhance session support If you have some feedback or would like to help with the project please contact me. Thanks -Jeff

announce: 'publish', a python blogger
by Russell Nelson 12 Apr '03

12 Apr '03

Been using my blogging software for a few weeks now. Seems to work fairly well. You give it a pile of .html files, and it publishes them in date order. Lets you modify the .html and when you next run publish, it makes a back-link to the previous version. Creates an index.html containing the front-page of the blog, an archive containing a list of all postings, and an rss.xml feed. Naturally, it's OSI Certified Open Source software. Look at the blog, and if you don't think it's too ugly, check out the link to the source. http://angry-economist.russnelson.com -- --My blog is at angry-economist.russnelson.com | If war is the answer, then Crynwr sells support for free software | PGPok | the question must be truly 521 Pleasant Valley Rd. | +1 315 268 1925 voice | horrific.

Syck 0.15 -- YAML extension for Python
by why the lucky stiff 11 Apr '03

11 Apr '03

Over the last few months, I've been developing a YAML parser in C which loads data directly into Python native structures. I imagine some of you have used Steve Howell's PyYaml. This extension is much swifter and quite competitive with Pickle/cPickle. Release notes are in the YAML below, so if you don't have a clue what I'm talking about, then I'm sure you can linkhop until it makes sense. --- released: { name: Syck, version: 0.15 } for: [ Ruby, PHP, Python ] by: why the lucky stiff about: > Syck is a YAML parser, an extension for scripting languages, written in C. So what is YAML? YAML is a new language for data. Describe objects in plain text. Load the data into your scripting language as arrays, dictionaries, classes, or primitives. links: YAML: http://www.yaml.org/ YAML Cookbook: http://yaml4r.sf.net/cookbook/ YAML Type Repository: http://yaml.org/type/ YAML Specification: http://yaml.org/spec/ Syck: http://www.whytheluckystiff.net/syck/ Syck Benchmarks: http://www.whytheluckystiff.net/arch/2003/03/19 Tarball @ SourceForge: http://aleron.dl.sourceforge.net/sourceforge/yaml4r/syck-0.15.tar.gz status: > Syck is about 60% compliant with the YAML spec. Most of the remaining issues deal with whitespace. Syck also doesn't yet support any of the shortcut syntax optimizations from the specification. The extensions are quite usable, though. Ruby, PHP and Python can load from a string containing YAML. Ruby also has support for stream loading from any IO object. benchmarks: > Syck is quite speedy, although not as swift as most language's native serialization. Syck runs at about: 30-35% of the speed of Ruby's Marshal. 15-50% of the speed of PHP's deserialize(). 600% of the speed of Python's Pickle. 33-40% of the speed of Python's cPickle. (Based on various types of structured data.) installation: > Syck contains working extensions for the Ruby, PHP, and Python languages. Each requires compilation of the libsyck library, followed by compilation of the extension. To compile libsyck, first download libsyck. tar xzvf syck-0.15.tar.gz cd syck-0.15 ./configure make sudo make install To install the Ruby extension: cd ext/ruby/ext ruby extconf.rb make sudo make install To install the Python extension: cd ext/python python setup.py build sudo python setup.py install To install the PHP extension: sh make_module.sh sudo make install (if you weren't root during make_module.sh) php -q syck.php examples: | To load this document in Ruby: ($:~)$ irb >> require 'syck' => true >> yp = YAML::Syck::Parser.new( {} ) => #<YAML::Syck::Parser:0x8058530> >> yp.load( File.open( 'syck-0.15.yml' ) ) => {"status"=>"Syck is about 60% compliant ..."} To load this document in PHP: ($:~)$ php -a Interactive mode enabled <? dl( 'syck.so' ); print_r( syck_load( implode( '', file( 'syck-0.15.yml' ) ) ) ); ?> .. php then outputs ..

ANN: python-ldap-2.0.0pre08
by Michael Ströder 11 Apr '03

11 Apr '03

HI! Find a new pre-release of python-ldap: http://python-ldap.sourceforge.net/ python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. It mainly wraps the OpenLDAP 2.x libs for that purpose. Additionally it contains modules for other LDAP-related stuff (e.g. processing LDIF, LDAPURLs and LDAPv3 schema). Download link: http://prdownloads.sourceforge.net/python-ldap/python-ldap-2.0.0pre08.tar.g… Changes since 2.0.0pre07: ldap.schema: * For backward compability with Python versions prior to 2.2 Lib/ldap/schema/tokenizer.py and Lib/ldap/schema/models.py use (()) instead of tuple() for creating empty tuples.
